Subject: [SCSI] don't kfree an initialized struct device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=12fb8c1574d7d0c262d2f4c667047889c4f27ebe;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

[SCSI] don't kfree an initialized struct device

This patch (as1359) fixes a bug in scsi_alloc_target().  After a
device structure has been initialized (and especially after its name
has been set), it must not be freed directly.  One has to call
put_device() instead.
